ROLLER-SKATE.

SPECIFICATION forming part of Letters Patent No. 296,358, dated April 8, 1884:.

(No model.)

To all whom it may concern:

Beit known that I, J AOOBV. Rowmzrnacitizen of the United States, residing at Richmond, in the county of Wayne and State of Indiana, have invented certain newcand useful Improve ments in Roller-Skates, of which the following is aspecification, reference being had therein to the accompanying drawings.

My invention relates to that class known as roller-skates, and has for its object strength, durability, cheapness, lightness, and efficiency. The device used enables the skater to adjust at will the tension on the elastic spring, which tension is produced by the adjustment of the post, by which, together with an eye-pivot secured by pin and washer, the truck-hanger is attached to the bracket, which is fastened to the foot-piece. The hanger may be removed by the skater by simply withdrawing the pin without taking the skate from the foot. The washer surrounding post has a lug to secure pin, as shown, or a hole into which a pin may pass, or any other method of holding the same, though I prefer the lug. Other devices might be used in the place of the pin and washer that would answer the same purpose; but I prefer the pin and washer.

I In the accompanying drawings, Figure 1 represents a side elevation of the front part of a roller-skate, with my improvements applied thereto. Fig. 2 is a longitudinal vertical section of the same. Fig. 3 is an inverted plan of the bracket attached to the foot-piece. Fig. 4 is the eye-pivot. Fig. 5 is the washer with lug used in conjunction with the pin. Fig. 6 is the adjustable post, with pin inserted near the outer end. Fig. 7 is' the hanger towhich the rollers are attached, and also having a flange or rib on its upper surface.

Similar letters of reference indicate corresponding parts.

A represents the foot-piece of a skate, as shown in Figs. 1 and 2.

B represents the metal bracket, as shown in Figs. 1, 2, and 3.

I represents the post, as shown in Figs. 1, 2, and 3.

L represents a support, as shown in Figs. 1, 2, and 3. Y

0 represents the adjustable post, as shown in Figs. 1, 2, 3, and 6.

D represents the eye-pivot, as shown in Figs.

1, 2, and 4..

E represents the washer, as shown in Figs.

1 and 2, and more fully in Fig. 5. p

K represents the lug on washer E, as shown in Figs. 2 and 5.

F represents the and 6.

G represents the hanger, as shown in Figs. 1, 2, and '3.

N represents the pivot, as shown on hanger G in Figs. 2 and 3.

1 represents the opening, as shown in Fig. 2, and dotted in Fig. 7.

S represents the rollers, as shown in Figs. 1 and 2.

T represents the axle, as shown in Fig. 7.

H represents the flange, as shown in Figs. 1, 2, and 7.

0 represents the elastic spring, as shown in Figs. 1, 2.

V represents the hole in which pin F is inserted, as shown in Fig. 6.

J J represent the grooves in post I, as shown in Figs. '2 and 3.

W represents the hole in post I, as shown in Fig. 6.

The bracket B is constructed with post I, provided with grooves J J, passing each other, so as to form in the sand the hole W, for the reception of the pivot N of hanger G. It also has the form L, to receive the post 0. The under face, R, is provided with flanges M M, forming part of the seat for the elastic spring (3.

The hanger G is provided with flange H, completing the seat for the elastic spring 0, when said hanger is adj nsted, as shown in Figs. 1 and 2. The hanger G is also provided with pivot N, to be inserted and rest in hole Win post I. ,The hanger G is further provided with opening or socket F to insert the pinnal bearing of eye-pivot D.

The eye-pivot D is provided with a pinnal bearing on its outer surface running at right angles with the eye or hole, so that when placed on the post 0, and inserted in the opening or socket P in the hanger G, it will make a perpin, as shown in Figs. 1, 2,

10 tion to be more rigid or flexible, as the operfect bearing, and also allow the hanger G to have a rocking motion.

The washer E is provided with the lug K, tohold in place the pin F when inserted through the post 0. By this mode of fastening the eyepivot to the post 0 it permits the post of being adjusted into or out from the bracket B, thereby pressing the hanger G against the elastic spring, causing the rocking or tilting moator may desire.

Having thus fully described my said inven-- tion, what I claim as new, and desire to secure by Letters Patent, is

l. The adjustable post 0, in combination with the bracket B, eye-pivot D, and pin F, substantially as set forth.

2. The adjustable post 0, in combination with bracket B, eye-pivot D, pin F, and washer E, with lug K, holding the pin in position, substantially as set forth.

3. In a roller-skate, the combination of the foot-piece A, the bracket B, having post I, and adjustable post 0, and flanges M M, with hanger G, having flange H, the elastic spring 0, pivot N, eye-pivot D, washer E, having lug K, and pin F, all constructed substantially as and for the purpose set forth.

a In testimony whereof I affix my signature in the presence of two witnesses.

JACOB V. ROWLETT.
